PLATE XXIL COULMAN ISLAND. 



From photographs by R. W. SKELTON (Sk. 58b and 58c, ^-plates), Jan. 15, 1902 , 

 taken from the N.-E. (Map A.) 



The various points of interest about the piedmont-glaciers * of Coulman 

 Island are described under Plates XXIII. to XXVI., where will also be 

 found references to Mr Ferrar's report upon the same, and to Captain Scott's 

 work. Attention may be drawn here to the extent of the ice-cap of 

 the island, a feature which is lost in the pictures taken close inshore. This 

 ice-cap is considerable, and even more so when viewed from the S. and W. 

 (see Ross, Voyaye to the Antarctic Regions, vol. i., p. 199), where it comes far 

 lower, and is apparently considerably deeper. Compared with the ice-cap of 

 the Balleny Islands, however (see Plate CXXVIII.), it may be taken as a proof 

 that in S. lat. 67, i.e., at the Balleny Islands, the deposition of snow is greatly 

 in excess of that in S. lat. 73 30', i.e., at Couiman Island. 



* "Piedmont-glaciers are formed by ice crowding on to a coastal plain at the foot of a mountain 

 range. In South Victoria Land three types are distinguished : () normal piedmonts-on-land ; 

 (6) piedmonts-aground; (<;) piedmonts-afloat." Ferrar, Nat. Hist. Hep., vol. i., p. 63.
